Abstract
The research focused on the role of digital elevation models (DEM) in estimating topographic variations affecting the suitability of agricultural land. To create an effective geographical database, a comprehensive spatial analysis of spatial information layers must first be carried out, focusing on their accurate representation on maps based on remote sensing data. This approach will enable the production of maps that will help to competently assess and regulate the use of agricultural land. These maps will be formulated by identifying, evaluating and classifying agricultural land in accordance with the characteristics of the environment in the study area. The results showed that the land suitability rating, specifically the unit of the agglomeration plain, was within the high suitability category with an area of 51.7 square kilometers. In contrast, the lowest proportionality was found in the unit of mountain ranges (ridges), covering 25.1 square kilometers of the total area of the study area of 181.3 square kilometers. These results illustrate the significant differences in the suitability of agricultural land based on the terrain and the local environment.
